Deck up 

Jump out of swimming pool and jump back in and keep swimming, like burpee sets in between swimming sets. The goal is to keep heart rate high. Pro tip: if someone asks are you finished, yell no.

Upper Deck Deluxe

Where you do a standard Upper Decker (take a dump into the Upper toilet tank), BUT you have disconnected the chain beforehand so that some poor sap has to reach into your poop soup to even flush it.

That bitch pissed me off so bad, I got her back with a full upper decker deluxe so she'd have full shit hands after fixing it.

v. The leaving of fecal matter in the tank of ones toilet, turning the water brown. Primarily done as revenge or a drunken practical joke, but sometimes in an emergency when the bowl is clogged.

n. The shit that is left in tank during such an act.

I got so wasted last night I upper decked Sean, his bathroom is going to stink for weeks.

Slatering the upper deck 

This technique is for the most skilled of slaterer's. One must be nimble and quick in order to accomplish this feat. It involves combining the classics "slatering" and the "upper decker." You sit on the top of the toilet in the AC slater position (from saved by the bell) and take a hot steamy dump in the upper deck.

Jorge: Hey man, what's wrong. Why is your face all bruised on your left side?

Carlos: Shit man, I was slatering the upper deck on your can and I fell off.

Jorge: What the hell does that mean man. What's that brown shit on your shirt and pants.

Carlos: Shit.

Jorge: You are f'd man. Why do I hang out with you.

upper deck grumpy blumpkin 

When a man is taking a shit in the toilet tank while receiving a blowjob from a woman who is shitting into the toilet bowl but reversed and facing the tank.

James Bond went to the Opera and met Bridget Jones, they proceeded to the rest room where they engaged in an Upper Deck Grumpy Blumpkin.
